, The general object is toprovide a frame and sash which areimpervious'to' weather conditions, is practically air tight and lockedagainst opening from the outside when closed, and is secure againstaccidental movementfrom any causewhenopen. f 10 A further object is toprovide a small primary opening" without raising the lower part of thesash out of its sealedpositiom thus to provide some ventilation andstill prevent ingress of rain. snow or sleet under any weatherconditions, vand 16 whereby in the other open positionsthe'sash willprevent ingress of rain, snow orsleet except in very severe windconditions and a sash which will prevent a harmful draft by'deflectingall of the incoming air upward. p, I 4 I 'An important object of ourinventionjis' to provide a ventilating window which 'jcannotfbe moved or'jarre'dfloose from any" position nor rattled by the action of the wind,and wherein any position it may be left' in, is practically a 25 lockedposition. 4 J A still further object is to provide a sash which may be;raised and swungl inward from] the top without being raised above' thetop jof' the frame: I thus afvjery low ceiling willfnotiprevent a full30 Op in thW Q With thetfore'go'ing and other objects inview ourinvention resides in' features of construction. the parts andcombinations" thereof, as hereinafterfset forth and cilaimed and shownin the 35 faccompanyingdrawingswhiht. e i .1 isfa' front 'elevationfof.oneforrn, 0 our improved: frameiandvjsash; ,,.Fig. 2 is a side sectionalview of maiden 'as illustrated in Figure, 1, 1 taken fon "line of Q pig.3 is a iraction'alsection off ef:d'ev ii;e taken onjline 3-3 of Figure'1..'

Weprovide a sashmade from barssimilarto the 'frame bars comprising thebottom rail jll, top rail l5 and side rails"l6l6; These four 10 membersare preferably miter joined and welded slm'ilar to. the frame. The sidemembers ll and I '6 are positioned, when the window is closed, asclearly illustrated in Figure 7; Theltop header l3 and top rail l5farepositioned when thevwin- 16 dow is closed,as illustrated in Flg ure a hbottom sill lo andithebottomrail I! are ,051+ tioned when the window isclosed, asllclearly illustrated in Figures'2 and 3. .1, H p I Thus itwill be seen that the, twofframes have 20 the same depth, whereby whenthewin'dowlf is closed, thereare two spaced andsealed contacts, one", onthe outside and one on' theinside and that we provide novelmeans whichact to tightly I hold these contacting, e bersto e her, as: will Q'A'sja matter of. lconveniencewe have illustrated our sash; havin six glasspanes. Clearly the sash and frame'may be mademto a commodate Ianynurnber and any sized panes an while,thev device. as, illustrated inFigure .1 is higherthan its width, the usualwindow for; the presentpurposeis somewhat greater in width than in height. It wiilbe noted byvscrutinizing Figures 5 and 8 p that. I our,improved}sash is opened,inwardly by swin in t e top awa from; th fr me n lift: ing the {sashfrom the bottom. The desired relaative openings .above and. below, thesash are secured by the length and positionof connecting links as willhereinafter appear. 1 The incom- 40 ing air at thetop .openingisdirected upward thus forming a slight; yacuum, below; the ,sash vwhichtends to also direct the air upward, which enters below the sash, thus.:preventing harmful, drafts near-the fioor.

; Weprovidean angle bar vi 8, which {is secured to and positioned onsill. l0, as =illustrated'in;1?ig, ure 3, and a similar angle bar |9 ispositioned similarly onsidejambs llll. Bars lfltermi nate as at go, I aportion, of a the inwardly .extend- ,lipjof I the angle" being bent,outwardly as l at zl thus to g a closure t the end ofthe guide channelformed by member l9. I .j rririe ow' i gure 1 a d 6;. '\wr;=., p'vldetwd links 2525, each being 'pivotally' se- 5 cured at their upperends to members II as at 26, the washer 21 answering as a suitablespacer between the two members. The lower ends of links 25 are pivotallysecured to side rails 18 as at 28, a washer 29 acting as a suitablespacer; thus when the sash is lifted, the upper end will swing away fromthe frame as illustrated in Figures 5 and 8.

We provide a drip cap 30 which is secured to member II and looselyembraces the outer flange of member II when the window is closed. asillustrated in Figure 3. We also provide brackets 3| which are securedto the bottom of member 30, as illustrated in Figures 2, 3 and 5, eachhaving projections 32 which extend into the channel formed by member l3,thus to prevent the lower end of the sash from swinging inward and awayfrom the frame.

We provide angle guides 33 which are secured to members l3 and IS, therear end being positioned whereby when the sash is lowered, lugs 32 willcontact member 33 and force the sash outwardly into its sealed position,as illustrated in Figure 3.

We provide means for locking the upper end of the sash into position asfollows:

Spaced arms 35-35 are suitably secured to top header l3. as illustrated,each having cut out notches 36 and 35' on their under sides. Spacedbrackets 33-38 act as hinges for the upper ends of depending loops 31,as illustrated. A loop extension 39 is suitably positioned to enternotches 36 and 36 when loop 31 is in the position shown in Figure 2, andto be disengaged when loop 31 is moved to the position shown by dottedlines in Figure 5. A spring latch 43 acts to lock loop 31 to theposition shown in Figure 2. We provide a handle ll whereby the operatormay easily move the sash by grasping loop 31 with one hand and handle llwith the other.

It will be seen that when the window is closed and loop 31 is in theposition shown in Figure 2, the sash will be held in its sealed positionand if loop 31 is then moved to the position shown by' dotted lines inFigure 5, the top of the sash will be moved out of contact with theframe and that the sash may be further moved to a position where member39 will engage notch 36' whereby some ventilation is provided butwithout lifting the bottom of the sash out of its sealed position; thusclearly a heavy wind will not blow rain. snow or sleet into the buildingwhen the sash is in this position.

We provide stops 35 which are preferably positioned and shaped asclearly indicated in Figure 5; thus the sash may be moved so lugs 32will rest on either pair of stops as indicated in Figure 5. The weightand position of the sash and action of links 25 will cooperate to holdthe sash securely in either of the positionsprovided.

Thus is will be seen that the applicants frame and sash are light,strong. pleasing in appearance and especially adapted to the service forwhich they were devised. We have shown and described the preferredembodiment of our invention. Clearly many detail changes may be madewithout departing from the scope and meaning of the appended claims.

Having thus shown and described our invention, we claim:
